界: Encapsulation

封装即绘制强边界。在 Web 浏览器中，这可能意味着确保您的移动代码不会被其他移动代码滥用。在服务器上，这可能意味着区分已验证数据和未验证数据、区分一个用户的数据和另一个用户的数据，或者区分允许用户查看的数据和不允许用户查看的数据。

Flash Misconfiguration: Overly Permissive Custom Headers Policy

ActionScript

Abstract

程序定义了一个过于宽松的自定义标头策略。

Explanation

默认情况下，Flash 应用程序需要遵循 Same Origin Policy（同源策略），该策略可确保来自同一个域的两个 SWF 应用程序能够访问彼此的数据。Adobe Flash 允许开发人员通过编程或 crossdomain.xml 配置文件中的相应设置来更改该策略。从 Flash Player 9,0,124,0 开始，Adobe 还引入了定义 Flash Player 可以跨域发送的自定义标头的功能。但是，在定义这些设置时应小心谨慎，因为当过于宽松的自定义标头策略与过于宽松的跨域策略一起应用时，将允许恶意应用程序将其选择的标头发送到目标应用程序，从而可能导致各种攻击，或导致不知道如何处理接收到的标头的应用程序在执行中出现错误。

示例 1：以下配置显示了如何使用通配符指定 Flash Player 可以跨域发送的标头。


  <cross-domain-policy>
    <allow-http-request-headers-from domain="*" headers="*"/>
  </cross-domain-policy>

使用 * 作为 headers 属性的值表明可以跨域发送任何标头。
